A linear drain group

ABSTRACT

A linear drain group of fluids from an environment having a collection channel of fluids to be drained includes a cover body, superimposed on the collection channel, and a plurality of support feet coupled to the cover body and arranged resting on the collection channel to support the weight of the cover body. A discharge unit has a drain hole located on the bottom of the collection channel and shaped to allow drainage of the flow of fluids. The collection channel has a plurality of shaped reliefs emerging from the bottom so as to provide the support feet with a base in elevation with respect to the bottom. The shaped reliefs are arranged in succession on at least two parallel orders and a plurality of areas of the bottom are interposed between each order to limit the overall dimensions of the reliefs.

FIELD OF APPLICATION

The present invention is applicable to the field of construction and, in particular, relates to elements belonging to showers.

More in detail, the present invention relates to a linear drain group of fluids from environments.

BACKGROUND ART

Recently, in the context of the drainage systems of environments which envisage the evacuation of liquids, for example showers, the use of linear drains has spread in place of the classic rounded or square-shaped drains.

This shift in favour of linear drainage systems finds reason, first and foremost, in an aesthetic choice. In fact, the possibility of being able to adapt and configure drains in synchrony with bathroom finishes and the peculiarity of the shapes thereof allow an aesthetic enhancement of the environment to the detriment of the use of traditional drains.

Furthermore, linear drains also have functional and hygienic advantages since the drain surface is conveniently accessible and consequently easily cleanable. In addition, the lengths can be adapted to any shower type and size.

Generally, such linear drains are composed of a water collection channel to which a cover body is coupled.

One of the problems encountered during the installation of linear drains is in arranging the cover at the floor level of the shower floor so that there is no unevenness, steps or the like, both for aesthetic reasons and to limit any injuries to users.

To overcome such difficulties, support elements of various heights capable of supporting the loads in operation and adapted to position most of the coatings at the desired height are generally used.

However, such support elements are generally positioned inside the collection channel and cause some drawbacks to the drainage of fluids.

In fact, on closer inspection, the presence of elements designed to raise the cover inside the channel to the desired height reduce the capacity of the channel itself. In other words, during the operation of the shower the fluids, which flow to the sides or through the cover body, flow inside the collection channel towards a drain hole typically connected with the plumbing. The aforementioned presence of the support elements reduces the hydraulic section of the channel and therefore accordingly decreases the capacity and flow rate.

Furthermore, the support elements, due to the shape thereof, tend to trap/jam residues of dirt accumulated in the shower tray such as, for example, hair transported by the flow of fluids along the channel, with the risk of obstructing the channel itself or the drain hole.

In order to overcome such drawbacks, linear drains are present in the known art which have collection channels provided with steps along the lateral perimeter, or along part thereof. Such steps allow the cover body to rest thereon, directly or by interposing support elements therebetween, so that there are no further objects inside the collection channel.

However, such steps present in the known drains do not allow to overcome the problems regarding the reduced hydraulic capacity of the collection channel; in fact, although eliminating the risk of blocking residues, the steps are positioned inside the channel similarly to the support elements, so they also reduce the hydraulic section of the channel. Moreover, since such steps are continuous and positioned along most of the channel itself, the hydraulic section and the collection capacity are greatly reduced.

Furthermore, the installation of the steps must consider the position of the drain hole as a constraint. Consequently, the known drainage systems have steps positioned at spacings such as to cause the bending of the cover bodies in operation.

In addition, the steps make it difficult to arrange the cover at the height of the floor surface, as they are not adapted to any thickness of the coating, which depending on the solution chosen has different dimensions.

Presentation of the Invention

The object of the present invention is to provide a linear drain group of environments which envisage the evacuation of liquids which allows at least partially overcoming the drawbacks highlighted above.

In particular, an object of the present invention is to provide a linear drain group of environments which envisage the evacuation of liquids, such as a shower, which minimizes the reduction of the hydraulic capacity compared to the known equivalent drainage systems.

Another object of the present invention is to provide a drain group which eliminates, or at least limits, the risk of obstruction of the collection channel due to the blocking of residues transported by the drained fluids.

A further object of the present invention is to provide a linear drain group which allows to limit, or even eliminate, the bending of the cover body due to the loads in operation.

Another object of the present invention is to provide a drain group adapted to position the cover body at the floor level of the shower tray regardless of the coating thickness.

Said objects, as well as others which will become clearer below, are achieved by a linear drain group of a shower according to the following claims, which are to be considered as an integral part of the present patent.

In particular, it is provided with a collection channel of fluids to be drained and comprises at least one cover body superimposed on said collection channel and shaped to achieve the aesthetic coverage thereof. The cover body is also shaped to allow the flow of fluids to be drained towards the channel.

According to an aspect of the invention, the drain group also comprises a plurality of support feet coupled to the cover body and arranged resting on the collection channel to support at least the weight of the cover body.

According to a further aspect of the invention, it also comprises at least one drain hole located on the bottom of the aforementioned collection channel and shaped to allow the flow of fluids to be drained.

Furthermore, according to another aspect of the invention, the collection channel comprises a plurality of shaped reliefs emerging from the bottom of the collection channel so as to provide the support feet with a base in elevation with respect to the bottom of the channel.

According to a further aspect of the invention, such shaped reliefs are arranged in succession on at least two parallel orders and a plurality of areas of the bottom are interposed between the reliefs of each order so as to limit the overall dimensions of the reliefs on the same bottom of the collection channel.

As mentioned, advantageously, the reliefs emerging from the bottom of the channel are arranged to avoid, or at least limit, the formation of deflections on the cover bodies due to the bending imprinted by the loads in operation.

Still advantageously, the shaped reliefs being arranged only in the positions necessary to maintain the structural integrity of the cover body, therefore allow to minimize the reduction of the hydraulic capacity of the collection channel compared to the known equivalent drainage systems.

Furthermore, such shaped reliefs are shaped so as to eliminate, or at least limit, the risk of fluid flow obstruction due to the presence of residues transported by the fluids themselves.

According to another aspect of the invention, such shaped reliefs are arranged in offset rows such as, for example, according to a quincunx arrangement.

Advantageously, the arrangement of the reliefs in offset rows allows to reduce the density thereof inside the bottom of the collection channel, so as to further minimize the reduction of the hydraulic capacity of the latter, without compromising the bending resistance of the cover body.

According to a further aspect of the invention, the support feet are coupled to the cover body by screw means so as to allow a continuous adjustment of the height of the cover body itself.

Advantageously, the adjustment by screw means is carried out continuously and therefore allows the cover to be arranged at the floor level of the shower tray regardless of the thickness of the visible coating.

DETAILED DESCRIPTION OF SOME PREFERRED EMBODIMENTS

With reference to the aforementioned figures, a linear drain group 1 of fluids from an environment is described herein, such as a shower, having a collection channel 3 of fluids to be drained.

In particular, it comprises a cover body 5, a plurality of support feet 6 and a drain hole 7 located on the bottom 10 of the collection channel 3 and shaped to allow the flow of the fluids to be drained.

Obviously, the number of drain holes present should not be considered limiting for different embodiments of the invention.

According to the embodiment of the invention which is described, the aforementioned bottom 10 of the collection channel 3 is inclined so as to have a slope such as to direct the flow of fluids towards the drain hole 7.

Advantageously, the inclination of the bottom 10 allows a rapid flow of the fluids to be drained so as to limit stagnation inside the channel 3. However, the execution of the bottom of the collection channel is not to be understood in a limiting sense for different variants of the invention where, for example, it is a horizontal plane.

According to an aspect of the invention, the cover body 5 is superimposed on the collection channel 3 and is shaped to obtain the aesthetic cover thereof, i.e., the visible part of the drain group 1. Furthermore, such a cover body 5 is shaped to allow the flow of fluids to be drained towards the channel 3.

According to the described embodiment, the fluids to be drained flow to the sides of the cover body 5. Obviously, such an aspect should not be considered limiting for different embodiments of the invention, where, for example, the fluids to be drained flow towards the channel through openings present in the cover body itself.

According to another aspect of the invention, the support feet 6 are coupled to the cover body 5 and are arranged on the collection channel 3 to support the weight of the cover body 5 itself and of further loads in operation.

According to the described embodiment, the feet 6 are coupled to the cover body 5 by screw means 12 so as to allow a continuous adjustment of the height of the cover body 5 itself.

Advantageously, the possibility of continuously adjusting the height of the support feet 6 makes it possible to easily arrange the cover body 5 at the floor level of the shower tray, avoiding the presence of rises or cracks such that there is a risk of injury to users.

Still advantageously, the presence of screw means 12 allows the cover body 5 to be positioned at the desired height regardless of the thickness thereof.

Obviously, such an aspect must not be considered limiting for different embodiments of the invention where, for example, the height of the cover body is adjusted by means of telescopic elements or in the case where the support feet adjust the height by discrete levels.

According to a further aspect of the invention, the collection channel 3 comprises a plurality of shaped reliefs 15 emerging from the bottom 10 of the collection channel 3 so as to provide the support feet 6 with a base in elevation with respect to the aforementioned bottom 10 of the channel 3.

Furthermore, such shaped reliefs 15 are arranged in succession on at least two parallel orders and a plurality of areas 16 of the bottom 10 of the collection channel 3 are interposed between the shaped reliefs 15 of each order.

According to the embodiment of the invention which is described, such reliefs 15 are shapes, made for example by moulding, of the collection channel 3. However, the execution of the shaped reliefs is a feature which should not be understood in a limiting sense for different variants of the invention where, for example, they are additional elements stably coupled to the bottom of the collection channel.

Advantageously, the shaped reliefs 15 are arranged to eliminate, or at least limit, the bending of the cover body 5 following the application of loads in operation.

Furthermore, the reliefs 15 of the invention have limited overall dimensions and this still allows, advantageously, to minimize the reduction of the hydraulic capacity of the collection channel 3 compared to the known equivalent drainage systems.

Still advantageously, the shaping of the reliefs 15 emerging from the bottom 10 of the channel 3 allows to eliminate, or at least limit, the risk of obstruction of the fluid flow due to the blocking of residues transported by the fluids themselves.

In addition, the presence of the areas 16 of the bottom 10 interposed with the shaped reliefs 15 still allows, advantageously, to minimize the overall space occupied by the reliefs 15 themselves in order to reduce the hydraulic capacity of the collection channel 3 as little as possible.

According to the embodiment of the invention which is described, the shaped reliefs 15 are arranged in offset rows such as, for example, according to a quincunx arrangement.

Advantageously, the arrangement of the reliefs 15, or part thereof, in offset rows allows to reduce the density thereof inside the bottom of the collection channel 3, in order to further minimize the reduction of hydraulic capacity of the latter, without compromising the bending resistance of the cover body 5.

As regards the cover body, according to the embodiment of the invention which is described, the cover body 5 comprises through holes 23.

Advantageously, the through holes 23 allow to obtain a lower-weight cover body 5 and, given the use of a lower amount of material, to reduce the manufacturing costs of the drain group 1.

Obviously, the presence of the through holes and the number thereof are features which should not be understood in a limiting sense for different variants of the invention.

Furthermore, according to an embodiment variant of the invention not shown in the figures, the cover body comprises a tray and/or an aesthetic coating typically, but not necessarily, tiles adapted to be arranged in the tray itself.

Advantageously, the tray and coating make it easier to install the drain group. Still advantageously, the tray allows to receive any coating resting thereon.

However, the embodiment of the cover body is a feature which should not be understood in a limiting sense for different variants of the invention where, for example, it is made in a single body.

In light of the foregoing, it is understood that the linear drain group of the invention achieves all the intended objects.

In particular, the drain group of the invention allows to minimize the reduction of the hydraulic capacity of the collection channel.

Furthermore, it allows to limit, if not eliminate, the residues transported by the fluids drained and retained in the collection channel.

In addition, the drain group of the invention allows to avoid, or at least reduce, the bending of the cover body due to the loads in operation.

Finally, the discharge unit of the invention allows to adjust the height of the cover body, so as to arrange it at the level of the floor surface, regardless of the thickness of the body itself.

The invention might be subject to many changes and variants, which are all included in the appended claims. Moreover, all the details and steps may furthermore be replaced by other technically equivalent elements, and the materials may be different depending on the needs, without departing from the protection scope of the invention defined by the appended claims.
